SPECIFICATION forming part of Letters Patent No. 411,524, datedSeptember 24, 1889.

Application filed July 6, 1889. Serial No. 316,713. (N0 model.)

T0 64% whom it may concern.-

Be it known that I, GEORGE W. JOHNSON,

of Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in I-Ieeling-Machines; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanyingdrawings,and to the letters of reference marked thereon, which form apart of this specification.

' This invention relates to improvements in shoe-heeling jacks orshoe-last supports employed in applying heels to shoes in theirmanufacture.

The invention consists in the several features of novelty hereinafterdescribed, and

more particularly pointed out in the appended,

claims.

In the manufacture of shoes as now practiced it is customary toconstruct the shoe, up to the point of putting on the heel, upon aWooden last and then to remove the last from the shoe and insert asmaller last of metal. The metal last is applied to a support orstandard, commonly one of two standards, the other one of which supportsthe forward portion or toe of the last. The lastsupporting mechanism issometimes called a heeling-machine and sometimes a heelingjack. Thereason for substituting an iron for a wooden last is that the former ismore stable or can be more firmly held in place on the jack or heelingmachine under the heavy hammering or pressure to which it is subjectedin nailing on the heel, besides being adapted to clinch the nails bywhich the heel is secured. Wooden lasts are, however, sometimes providedWith metal heel-plates for the same purpose, as shown in Figure 1. Thesubstitution of one last for another in the progress of the manufactureof the shoe is, for some reasons, objectionable. Such substitution notonly requires the expenditure of time 011 the part of the workman, butit also more or less impairs the nicety of the shape of the shoegenerally. Moreover, the shape of the shoe is more or less impaired whenthe heel is being attached upon a substituted last, because the latter,not being as large as over which the shoe is first formed may be firmlyheld in place upon the machine and may therefore be retained in the shoewhile the heel is being attached.

Another feature of the invention consists in an improved construction ofan adjustable toe rest or support by which the last may be held firmlyupon the jack to receive the heel.

In the accompanying drawings, Fig. l is a side view of a heelingjack ormachine containing my improvements. Fig. 2 is a front view thereof. Fig.3 is a fragmentary en larged rear view, partly in section, of theheel-standard of the j aok having the lastsupporting attachment of myinvention there on. at 4 of Fig. 3. Fig. 5 is a rear View of the mainstandard of the jack, showing a modi fied form of mechanism foroperating the clamps which form part of my improvement.

In the drawings, A is the upper part of the rear or heel-supportingstandard of a heelingjack, which may be of any approved pattern. Thestandard A is here shown as being provided at its upper end with areduced portion or projection a, terminating at its lower end at ashoulder a, this projection being a part which is inserted in acorresponding recess in the peen of an iron last.

Fig. 4 is a horizontal section in the line Bis a sleeve fitted to theprojection CL of the standard A and closed at its upper end, where it issuitably formed to constitute a support or rest for the peen of thelast. The

posite sides of the rest-sleeve B. The lower portions of the arms C areshown in Figs. 2, 3, and 4 as being pressed outwardly by expandingsprings D, interposed between the arms and the standard A, while theupper ends a of said arms extend above the rest and are arranged to bearagainst the sides of the last. The springs D, having a constant tendencyto force the lowerends of the arms outward, cause their upper ends topress firmly against the last and to sustain the latter rigidly in itsupright position. In Fig. 5 a coiled spring f, surrounding the standardand bearing upwardly against an annular conical wedge E, which alsoembraces the standard between the lower ends of the arms 0, similarlyoperates to force the lower ends of said arms outward and to press theupper ends of the arms against the sides of the last.

The upper bearing portions 0 of the arms C are slightly rounded on theirouter lateral surfaces to permit their free insertion between the upperof the shoe and the sides of the last, and they are desirably elongatedhorizontally, as shown, to give more extended bearing upon the surfaceof the last. A vertical pin a rising from the shoulder ct of thestandard A, enters a corresponding hole in the lower face of the sleeveB and operates to prevent the rest from revolving about the standard A.

The device, as above described, including the. removable sleeve-rest B,illustrates this portion of the invention as an attachment which may beapplied to an ordinary standard vided at its upper end with verticaladjusting devices by which it may be lengthened and lowered so as tobring the peen of the last into square bearing upon the rest 13. To thisend the upper end of the rod E is provided with a'lateral enlargement e,having two vertical holes 6 6 through it, the latter of whichis=provided with screw-threads.

E is a toe-rest proper, provided with a shank e fitted to the hole 6 Eis a thumb-screw fitted to the screwthreaded hole a and rising beneaththe toerest E, as shown, so that in turning. said thumb-screw thetoe-rest is adjusted vertically to any desired height.

G represents a wooden shoe-last having a metal facing g upon its heelportion, by which are clinched the nails that are driven through theheel to secure the sameto the sole proper. I do not wish to be limitedto the precise means described for throwing the upper ends of thegripping-arms 0 into bearing upon the sides of the shoe-last, as it isobvious that other devices than those shown may be employed forproducing the desired result, nor do I desire to be restricted to theexact means shown for adjusting the independent toe-rest E.

' I claim as my invention- 1. In a heeling-machin e,and in combination,the standard A, provided at its upper end with a reduced portion a, apin a projecting from the upper portion of said standard, and a sleeveB, fitting over said projection a, and having a hole in its lower facefitting over the pin (1 whereby it is prevented from displacement, saidsleeve being provided with a flat top surface to receive the shoe-lastG, substantially as described.

2. The combination, with the toe-supporting standard E, provided with anapertured lateral enlargement or head 6', of the toe-rest E, providedwith a shank e fitted to a hole in the head, and an adjusting-screw ealso fitted to the head and arranged to adjust the toe-rest Vertically,substantially as described.

3. In combination, in a heeling-niachine, a suitable standard having areduced portion at its upper end, a sleeve B, fitting over said reducedportion and provided with a fiat top surface for the reception of theshoe-last, a

pin a on the standard A, fitting acorresponding recess in thesleeve-rest, whereby. the same is prevented from turning, grippingarms 0O, pivot-ed to the sleeve-rest, their upper ends extending above saidsleeve bearing against the sides of the last, springs bearing upon thelower ends of said arms for holding them normally pressed against thelast, and a vertically-adjustable rest, as E, adapted to support the toeof the last, substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses. v
